We need a simplified version to be spelled out for laypeople.
Is "the pilot put the plane into the ground" simplified enough?
Seanus - sadly, you've posted a link to someone who doesn't know what he's talking about.
The instrumentation was the latest and best, and included a standard ILS (Instrument Landing System) receiver which would guide the airplane to the edge of the Smolensk runway — providing the ILS receiver and ground based transmitters were reliable and working properly.
As I'm sick in the face of saying - what ILS? There certainly wasn't a "standard ILS" system installed at Smolensk-North.
There's other mistakes too, but this one kinda puts a hole in his credibility, don't you think?
Ah, what the hell - he also mentions that the outer marker was "2 kilometres from the runway" - which is yet another verifiable mistake on his part. Ahh...too easy :)
(I'm still waiting for a conspiracy theory that actually gets the facts right)
